AUXILIARY COUPLING DEVICE.

SPECIFICATION forming part of Letters Patent No. 742,720, dated October27, 1903. Application filed November '7, 1901. Serial No. 81,370. (Nomodel.)

To all whom it may concern:

Be it known that I, CHARLES II. MOLAUGH- LIN, a citizen of the UnitedStates, residing in the city and county of Philadelphia, State haveinvented a new and useful Improvement in Auxiliary Coupling Devices, ofwhich the following is a specification.

My invention consists of an auxiliary coupcar-couplings of the Janneytype, as will be hereinafter fully described and claimed.

Referring to the drawings, my invention consists, broadly, of anauxiliary coupling device having rigidly-connected interlocking heads atits ends that are adapted to auto- 0 matically interlock with couplingsof thefamiliar Janney type, having a pivoted knuckle and a guarc. Thesecar-couplings are usually constructed on what are known as MasterOar-Builders lines, andmy which is indicated as a whole by A, isprovided at each end with a coupling-head, which consists of arelatively rigid nose and guard to automatically interlock with thecoupling-arm of the pivoted knuckle and the guard of car-couplings ofthe type referred to. v

My coupling device can be made in various different forms-for instance,.for the purpose of coupling the car-couplings on a railroad-car and astreet-car or the couplings on two street-cars, or, again, the couplingson two railroad-cars-and in the accompanying drawings Ihave illustratedthe different forms of my auxiliary coupling devices that are adaptedfor these purposes. I will now describe the same in detail.

In Figs. 1 to 8 I have shown a coupling dc vice A as adapted to couple arailroad-car and street-car, the same comprisinginterlocking heads ateach end thereof, consisting, es= sentially, of noses E and F and guardsE and F either on Master Gar-Builders lines or closely conformingthereto I have shown the lookingheads corresponding in contour with acarcoupling when the knuckle is closed, so as to automatically coupletherewith. In the construction of coupling device A, I form a plate Bwith a wall 0, extending around and above and below the same, as bestshown in Fig. 8, and conveniently brace the walls 0 upon the plate B,for instance, by the ribs D, although it is understood that other formsof braces may be employed to strengthen the casting. I have also shown alongitudinal rib D extending between the rear portion of the walls 0 ofeach locking-head.

It is understood, of course, that it is necessary to provide means forsupporting the coup ling device upon one of the car-couplings not onlyto prevent the same from dropping, but

to allow the other car-coupling to automatically couple with thelocking-head on the other end of the coupling device, and I place thesemeans upon one of the heads, the same consisting conveniently of adownwardly-facing shoulder on the locking-head that engages an oppositeface on the knuckle of a car-coupling, and in the particular embodimentof these means in Figs. 1 to 8 I show the inner side of the nose E asprovided with 'a plurality of horizontal ribs and grooves. This nose Eis on the locking-head that is adapted to engage the car-coupling on thestreet-car, the type of street-car coupling being one having ribs andgrooves on the coupling-arm of its knuckle, as shown in Figs. 5, 6, and7, the said ribs and grooves J of the nose E interlocking with the ribsand As the car-couplings in general use are.

grooves II of the- ICO coupling-arm G of said car-coupling. Thus whenthe car-coupling and coupling device interlock, as shown in Figs. 5 and7, the coupling-block is supported. Also by the employment of aplurality of grooves,as I have shown, the coupling device A can beelevated sulficiently in the manner shown in Fig. 5 to be upon the samelevel as the oar-coupling H of the railroad-oar.

In Fig. 9 I have shown a coupling device K, that is designed forcoupling car-couplings, for instance, of two street-cars provided with atype of coupling shown in Figs. 5, 6, and 7 that is to say, the saidcoupling device-K is provided with the coupling-heads L, that areduplicates, each of said heads being provided with a nose M and theguard M, said noses being provided with the ribs N, corresponding to theribs J. (Shown in Fig. 1.)

In Figs. 10 to 13, inclusive, I have shown a coupling device P, that isespecially adapted for coupling the car-couplers of two railroad-cars,the same being provided with coupling-heads P, each of which is providedwith a nose Q and a guard R. The faces of the noses are plain, and toprovide means for supporting these coupling devices upon thecar-coupling I preferably attached to one of the noses a suitable deviceto form a downwardly-facing shoulder on the inside of the nose. This isformed by a member W, having a projection V extending into a socket T,formed in the nose, a springU being situcured to the nose.

ated within said socket and bearing against the member WV to press itinwardly. The said member is provided with an arm D, having a slot 0,through which extends the screw of pin D, by means of which it is se-Extending inwardly from the upper end of the member WV is a projectionA, the lower face of which forms the shoulderabove referred to and whichis adapted to rest upon the upper side of the knuckle of thecar-coupling to support the coupling device.

It will thus be seen that I provide a coupling device that not onlyinterlocks the carcouplings of the type referred to, but which isprovided with means that support the same upon such a car-coupling, andalthough. in the different embodiments'of my invention illustrated Ihave shown various ways to secure this result, yet except in the claimsfor the specific construction my invention is not limited thereto,for itis obvious that the broad principle of my invention can be variouslyembodied under the scope of the appended claims.

It will be apparent that changes may be made by those skilled in theart, and I do not, therefore, desire to be limited in every instance tothe exact construction herein shown and described.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is
